Switchboard Engineering Simplified
Introduction: High voltage switchboards are specialized electrical distribution equipment designed to handle higher voltage levels than standard switchboards. They are commonly used in industrial & commercial facilities, power plants, substations, and other applications where high-voltage electrical power connections are sanctioned by the local utility. Let us start with what is the relevant national and international … Read more
Background Internal Arc Faults can occur in low-voltage as well as medium-voltage switchgear panels. However, we have chosen to discuss the internal arc fault phenomenon in medium-voltage switchgear and its impact on human safety because of its severity in the latter case. What is an Internal Arc Fault? Very important to understand what this phenomenon … Read more
What is decision making? Decision making is a process of making choices from available alternatives or generating alternatives through a step-by-step process. Decision making is an act we do every day in our personal and professional lives to achieve certain objectives. Basic elements of decision making The first stage of decision making process is to … Read more
Introduction We have learned the fundamentals of Power Quality in our earlier article “Power Quality Basics”. We have also learned the importance of good Power Quality on Low Voltage distribution networks along with some basic calculations. Now we will go a little deeper and understand the implementation of power quality improvement methods. Power factor is … Read more
What is Power Quality? Power generated and used is with a sinusoidal wave characteristic at 50 Hz at a power factor close to unity. If it is free from other waveforms of voltage and current, then Power Quality is good. If it is mixed with other waveforms of voltage and current, then Power Quality is … Read more
Introduction A Sandwich Busway System is a means to transfer electrical power from one equipment to another equipment in a low-voltage electrical network. The other ways to transfer electrical power in an electrical network are bare or insulated solid conductors and cables. Here our topic of discussion is Sandwich Busways, its construction, and its advantages … Read more
Background Why do engineers need to know about basic financial terms? Traditionally engineers are supposed to do engineering which is their domain of expertise. Just go a little deeper and you will find that all our actions as an engineer have a definite financial impact. Let us understand this by an example. Consider the activities … Read more
Introduction Our discussion here will be limited to Medium Voltage Switchgear up to 33kV. Before we understand solid insulation switchgear technology, we will first go into the history of medium voltage switchgear solutions. If we talk of evolution of medium voltage solution, then we can broadly categorize them under two sections as given below: On … Read more
Background (Courtesy: Tricolite Electrical Industries Ltd) The validity period of type tests for switchboards are many a times debatable if it is older than five years. I am sure as an engineer you have also faced this challenge during some of your interaction with your clients. We all that power equipment undergo developmental stage before … Read more
Introduction (Source: coAmplifi) “Tick tock, tick tock, tick tock………”. This is not a short video app with a similar name but rather the clicking sound of the clock. It keeps on clicking despite whether we are using it productively or just letting it pass. So Time Management become a hot topic for professionals and trainers … Read more
